In one of his most vicious attacks yet against former Secretary of State Hillary Clinton, Donald Trump used a sexually derogatory remark in reference to her and said that her bathroom break during the last debate was "disgusting."

During a campaign event in Grand Rapids, Michigan, Trump referred to Clinton's performance in the 2008 election.

"Even a race to Obama, she was gonna beat Obama. I don't know who would be worse, I don't know, how could it be worse?" he told the crowd. "She was favored to win and she got [expletive], she lost, I mean she lost," he told the crowd.

"But I watched her the other night, it was hard, it was really hard because there were a lot of other things on better, including reading books and reading financial papers which I actually enjoy reading.”
